IMPROVEMENT IN KNITTING-MAGINB.

elle ttehule rcfmr tu in time Entert ment rnb making im nf tige same.

Be itknown .that I, K. PRAY,- of Holderness, inthe county-of Grafton,; and State of New Hampshire, Y

have invented new and useful Improvement in Knitting-Machines and Idoihereby declare that the follow-y ing is a full, clear, and exaetdescriptio'n thereof, which will enable others skilled in the art to make and use the same, reference .bengliad to the accempanyingdrawings, forming part oi' this specification, rin which--v Figure 1 represents plan view of a ring, constructed according to my improvement. Y

Figure 2 represents s. section of the s'ame. e

Figure 3 represents a side view, with a part broken away.

Similar 'letters of Areference indicate corresponding parts.

rJhe object of" this invention is to' provide means wherebyY the cams of' circular-knitting machines may be readily detached from the rings, when necessary to reit them or clean out the cam-groove, which sometimes'` becomes obstructed, without the necessity of taking the m'achine to pieces, or` displacing the needles, as must be done with the Vmachines as'no\v-censtructed. l e

It consists in making that part of the ring to which the cams are secured, detachablefrom the other part,

and providing a'segment of a ring to hold the needles in place while the said detachable part is removed.

- It frequently happens that the cams uecome worn, and require to be taken rout to be reiinished, and more *frequently it happens that the buttsor projections on the needles become broken, and lodge in the part ofthe groove whichpasses through theeamsg for which they'mustalso be taken out, and-which necessitates the taking the ring'o," the barrel, 'hy which the needles become displaced, involving the labor `ef replacing them when the cams are replaced,` one by one,'which consumes a great amount of time.`

In the 'drawings--- A represents a ring, which is provided vwith the detachable portion B, the ends of which are halved to the main part A, and secured thereto hy the screws a a, and to which the cams arcsecured in any suitable manner. @represents a segment of a ring, which issecured to thev ring A, extending across the space made by the removal efv the partlB, which maintains theA needles in their positions in the grooves of the barrel, while the saidpart B is removed.

Having-thus dcscribedhiy invention, claim as new, and desire to secure byLetters Patentl. The ring A, eonstrncted'with that part to which the earns are secured, detachable, vsubstantially as and for the purpose set forth.V i

2. The combination, with the r-ingA, having thc detachable part B, of the segment C, substantially as and for the purpose described.

E. K. PRAY.
